As a treatment for insomnia, sleep restriction therapy falls under the “behavioral treatment methods”. It also falls under the paradoxical concept of “less is more”. That may sound contradictory to you at first.
A paradox is, in fact, something that seems contradictory on the surface, but once you delve into the subject a bit you find that it makes sense.
Less is More
For example, I’ve been training for a marathon over the last several months. For a period of about six weeks I found that I was getting tireder and tireder, and my legs were aching all the time. I decided I was pushing too hard, so I backed off of my mileage and intensity. Instead of trying to run 70+ mile weeks I was only running 50 or so.
The result? After two weeks the pain went away, my energy picked up and I was able to slowly build the mileage back up to 60/week, and I was running faster. In my case, less running = more benefit.
The reason “less is more” is often true is because we have limited bodies and minds. We are designed to handle excesses for periods of time, but then we must have time to recover. If we eat too much for a few days we will gain weight if we don’t back off and return to a normal diet. If we exercise too long and too hard our bodies will begin to break down, until we back off and allow time to recover.
Similarly, our sleep can become disrupted because of a variety of issues, and the solution may be to back off. Sleep restriction therapy is a way of backing off temporarily and then slowly building back up to a normal level.
